Mostly Apple users are unaware to check their emails on i Cloud.
For the fresh users of Apple who are still confused that how to check i Cloud email, stop confusing because you just need to have an Apple ID account to access your emails.
The procedure to understand that how to check i Cloud mail can be tricky.
The answer worked for me and I am able to send and receive mail.
However, I continue to receive an error message from Windows 10 mail: "Your i Cloud account settings are out of date".
Do keep in mind if you have two-factor authentication setup for Apple ID you’ll need to verify each i Cloud login from a new web browser as a security measure.
